Re: Coldfire Boards

Your right, we do have M547x/M548xs, but I don't have a BDM module or
a USB JTAG module, which means if I make a bad u-Boot, my board is as
good as a brick, and I prefer my board non-bricked. Youpi has managed
to get u-Boot running on his board, but has yet to successfully run to
/bin/sh's execution. I've read some boards have the ability to change
the location of the IPL execution point to the second part of the boot
flash, but these boards don't seem the ability to do so. If I'm
mistaken, please point me to the right jumper so I can work out the
necessary memory map to generate patches for u-boot.
My method involves writing a root filesystem to the second flash chip,
and then using that to boot from. dBUG doesn't support automatic
booting, so this obviously is not ideal. In addition, the kernel can't
execute from flash*, which means it has to be manually loaded into
RAM. Also, I'm not specifying a proper MTD partition table thus its
not possible to have an initrd, and initramfs just crashs the kernel
* - I'm told 2.6.28 may have this feature at long last
If someone can point me to where I can buy a cheap BDM module, or a
cheap JTAG USB flasher (and where on the mini-ITX I need to connect
it), I can work out the proper partitioning and generate a nice binary
package which can later be used as the basis of d-i.
